Variations in the branching pattern of the internal iliac artery and its implications in trauma and surgery - a South Indian cadaveric study.

Background: The internal iliac artery (IIA) frequently shows variations in its branching pattern. Knowledge of its variations is helpful during gynecological and orthopedic surgical procedures.

Objectives: To observe the branching pattern of IIA in the human pelvises and discuss its clinical implications.

Vesico-obturator venous plexus - a rare termination of obturator vein.

Obturator vein usually terminates into the internal iliac vein. Its variations are the cause major bleeding problems in pelvic surgeries. We observed a rare variation in the termination of the right obturator vein.

Predictors of Adolescent Internalizing and Externalizing Mental Health Symptoms: A School-Based Study in Southern India.

Introduction: Mental illnesses are one of the major contributors to the overall burden of disease among the young. We investigated the predictors of emotional and behavioral problems among in-school adolescents in the Indian context.

Methods: Using stratified sampling, 1441 adolescents were recruited to participate in the study in Udupi taluk.

A rare additional lobe of cerebellum, projecting from its superior surface.

Human cerebellum plays a vital role in motor coordination, regulation of muscle tone and maintaining the equilibrium of the body. It seldom shows anatomical/morphological variations. Herein, we report the presence of a small additional lobe projecting out on the superior surface of the right cerebellar hemisphere in the para-vermal area in an adult male cadaver.

Sternocleidohyoid muscle: an unreported variant of cleidohyoid muscle.

Sternohyoid, sternothyroid, omohyoid, and thyrohyoid muscles are collectively known as infrahyoid muscles. These muscles frequently show variations in their attachments. Here, an extremely rare variant muscle belonging to this group has been presented.

Surgical and embryological perspective of a big loop of internal carotid artery extending laterally beyond internal jugular vein.

Knowledge of variations of the internal carotid artery is significant to surgeons and radiologists. The internal carotid artery normally runs a straight course in the neck. Its anomalies can lead to its iatrogenic injuries.

Partial duplication of tentorium cerebelli and complete duplication of falx cerebelli.

Variations of the dural folds and the dural venous sinuses are infrequently reported in the existing medical literature. Such variations in the posterior cranial fossa may pose difficulties in various analytical and surgical procedures of this region. We present a rare concurrent variation of the falx cerebelli and tentorium cerebelli that was detected during routine dissection of an adult male cadaver.

Double-bellied superior rectus muscle.

Congenital variations of extraocular muscles are rare. We report a double-bellied superior rectus muscle, observed in an adult male cadaver aged 70 years. The superior rectus muscle had two equal-sized bellies, which took separate origins from the common tendinous ring and united to form a common belly 1 cm before the insertion.

Two accessory muscles of leg: potential source of entrapment of posterior tibial vessels.

Accessory muscles can be found in any part of the body. In most of the regions, they go unnoticed. However, in some cases, they become symptomatic or of cosmetic concern.

Solitary osteochondroma in the body of the pubic bone: a cadaveric case report.

Osteochondromas develop as cartilaginous nodules in the periosteum of bones. They are the commonest benign tumors of the skeleton, generally observed in the long bones. Rarely, they are also found in the axial skeleton, flat bones of skull and facial bones.

Bilateral low origin of testicular artery: a case report.

The testicular artery is frequently subjected to radiographic imaging techniques such as angiography for diagnosis and treatment of conditions like epididymitis, testicular torsion, tumor, hematoma, and hydrocele and in cases of undescended testis. Radiologists and surgeons should therefore be aware of testicular artery variants. Although there are numerous studies and case reports that mention testicular artery variants, this is probably the first case, reporting a bilateral low origin of the testicular artery and discussing its probable embryological etiology.

Surgical and radiological importance of a rare cysto-duodeno-colic peritoneal fold.

It is quite common to see abnormal peritoneal folds in the abdominal cavity. Some of them might compress or strangulate the viscera and others might determine the direction of the flow of peritoneal fluid, pus or blood. Many unusual clinically important peritoneal folds such as Ladd's band, cysto-gastro-colic fold, omento-cystic fold, and cysto-colic fold have been reported earlier.

Variant Superficial Branch of Radial Artery along with Supplementary Tendons on the Dorsum of the Hand and Their Surgical Implications.

Variations of radial artery, in both its course and branching pattern in the anatomical snuffbox, are clinically significant for the plastic surgeons, cardiologists, and radiologists. Reports on its abnormal high origin and subsequent superficial course have been well documented. Herein, we report an unusual superficial branch of the radial artery given off before its entry into the palm by passing between the two heads of first dorsal interosseous.

High incidence of persistence of sacral and coccygeal intervertebral discs in South Indians - a cadaveric study.

The sacrum, by virtue of its anatomic location plays a key role in providing stability and strength to the pelvis. Presence of intervertebral discs in sacrum and coccyx is rare. Knowledge of its variations is of utmost importance to surgeons and radiologists.

Unusual and Unique Variant Branches of Lateral Cord of Brachial Plexus and its Clinical Implications- A Cadaveric Study.

Introduction: Adequate knowledge on variant morphology of brachial plexus and its branches are important in clinical applications pertaining to trauma and surgical procedures of the upper extremity.

Aim: Current study was aimed to report variations of the branches of the lateral cord of brachial plexus in the axilla and their possible clinical complications.

Materials And Methods: Total number of 82 upper limbs from 41 formalin embalmed cadavers was dissected.

A South Indian cadaveric study on obturator neurovascular bundle with a special emphasis on high prevalence of 'venous corona mortis'.

Surgical procedures in the pelvic region are very challenging because of the complex anatomy of this region. "Corona mortis" is a term used to describe retro-pubic anastomosis between the obturator and external iliac vessels. It is considered as a key structure as significant haemorrhage may occur if the vessels are cut accidentally during pelvic surgeries.

Evaluation of Numerical and Positional Variations of the Hepatic Veins: A Cadaveric Study.

Introduction: Hepatic veins are the major linking vessels between systemic and portal circulation. Numerical and positional variation of the hepatic veins can play a significant role during surgical interventions on the liver.

Materials And Methods: Gross anatomical study regarding the number and arrangement pattern of hepatic veins was undertaken on 88 adult livers which were stored in 10% formalin after the regular dissection classes.

Effect of sorafenib on sperm count and sperm motility in male Swiss albino mice.

The issue of male germ line mutagenesis and the effects on developmental defects in the next generation has become increasingly high profile over recent years. Mutagenic substance affects germinal cells in the testis. Since the cells are undergoing different phases of cell division and maturation, it is an ideal system to study the effect of chemotherapeutic agents.

Dangerous course and atypical termination of the splenic vein in relation to pancreas--a case report.

Context: Knowledge of variations of the vessels closely related to the pancreas adds greatly to the success of pancreatic surgery. Splenic vein is one of the vessels that are closely related to the pancreas. Its variations might not only change the haemodynamics in the vein but also cause unexpected bleeding during pancreatic surgery.

A lobulated spleen with multiple fissures and hila.

During our dissection classes, we observed a lobulated spleen with multiple hila and fissures. The spleen presented 4 hila and 5 deep fissures. The hila were seen on the visceral surface.

Eight prehilar branches of the right renal artery.

Imaging technology with its advancement in the field of urology is the boon for the patients who require minimally invasive approaches for various kidney disorders. These approaches require a precise knowledge of the normal and variant anatomy of vessels at the hilum of the kidney. During routine dissections, a variation in the branching pattern of the right renal artery was noted in an adult male cadaver.

Double gallbladder completely enclosed in a cystogastric fold of peritoneum.

Double gallbladder is one of the rare congenital anomalies of the gallbladder. Failure to detect an accessory gallbladder hampers diagnosis and treatment of cholecystitis, which might result in recurrent attacks of cholecystitis. In addition, presence of peritoneal folds extending from the stomach and duodenum to the gallbladder is very rare.
